In the six years since the last NAIT integrated amplifiers were released, our research and development team have worked on a range of amplifier improvements. The result is upgraded power amplifier sections for SUPERNAIT 3, delivering greater pace and intimacy to their musical delivery – whether it's driving a pair of loudspeakers or your favourite pair of headphones.

SUPERNAIT 3 has received significant performance upgrades, including a built-in phono stage, making it a perfect partner for turntables, as well as for streamers, CD players, or any other music source people want to enjoy with the signature Naim sound.

It also includes a Class A preamp output stage which doubles as a headphone amplifier and ceramic heatsink technology that minimises capacitive coupling between the chassis and output transistors for optimum sound quality.

Its inputs are each individually decoupled and hand-wired to minimise noise and interference while internal switching employs ultra-low-noise, constant current sources which are derived directly from the electronic design of the flagship NAC 552 preamplifier.

The SUPERNAIT 3 can be upgraded with our external power supplies, power amplifiers and even cabling upgrades to get the best from all sources. 


With our typical obsessive attention to detail – all in service of achieving the most authentic musical performance – the SUPERNAIT 3 benefits from the following features:

  • Class A headphone amplification
  • Alps Blue Velvet volume control
  • Reed relay input selection
  • Ceramic insulators for the power transistors
  • Galvanically isolated microprocessor control section
  • Microphonic-isolating PCB mounts

Step up from the NAIT XS3 to the SUPERNAIT 3 and you benefit from a range of superior features, all designed to deliver even better sound quality:

  • Full 24V DR module built-in: enjoy the purer power and performance improvement of Naim’s Discrete Regulation technology for the entire pre-amp stage.
  • Larger toroidal transformer in the power supply: provides greater power and speed of recovery
  • Additional leaded through-hole components in the signal path: further minimises negative effects of vibration and transient thermal conditions
  • Chassis-mounted input sockets hand-wired to the circuit boards: offers enhanced vibration isolation
  • Full Alps Blue Velvet balance control

Technology & Craft

The upgrades in more detail:

  • Our R&D team has found a way to more than double the speed of the voltage gain stage, which in turn doubles the rate at which the speaker output stage can react.
  • The second gain stage transistors have been optimised, so they no longer need to be shielded by a cascode stage transistor. Removing the cascode means less amplifier stabilisation is required: that doubles the slew rate and delivers an uplift in sound quality.
  • The phono circuit topology comprises 3 stages: the gain stage, passive equalisation and final gain and active equalisation. This enables excellent noise performance, extended RIAA equalisation beyond the audio band and great overload headroom.
  • All RIAA equalisation capacitors and the RIAA resistors are ‘through-hole’ mounted film designs, with low microphonic pickup and excellent transient performance. As phono stages are 1000x more sensitive than other inputs, this greatly benefits the sound quality.
  • Input impedance is 47kΩ in parallel with 470pF capacitive loading;  the gain is perfect for 5mV moving magnet cartridges.

"This added heft was present as soon as the Supernait 3 was up and running in my system. My first notes contained words like ‘grunty’ and ‘solid’ when discussing drums and bass guitars."

"Without compromising on the virtues of the earlier models, this is an amp that creates compelling and believable space around everything you ask it to play."
Hi-Fi Choice | SUPERNAIT 3 | Recommended Award , Nov 2019
"it effortlessly provides a high level of subtlety and is one of the most accomplished integrated amps I’ve heard and a true all-rounder"
What Hi-Fi? | SUPERNAIT 3 | 5 Star Review, Oct 2019
"We can’t think of a more capable alternative when it comes to rhythmic drive and precision. The Supernait 3 conveys the changing momentum of this music brilliantly, capturing the various mood changes between tracks with conviction."
HIFICRITIC | SUPERNAIT 3 | Audio Excellence Award , Sep 2019
"It’s pretty clear that this new Supernait is much more than a Mk2 with a phono stage bolted in...keeping the Supernait 3 firmly in place as a domestically acceptable way of achieving the best Naim can do, without filling the room with multiple black boxes."
The Ear | SUPERNAIT 3 | Editors Choice , Sep 2019
" The Classic series is still very much alive and kicking and the Supernait 3 is living, musical the beating heart of a music lover’s system, this integrated may just be the last amplifier most of us could ever want or need"
